0B-10 MAINTENANCE AND LUBRICATION
2) Proceed to till the circuit till mouth (11) as follow:
• Pour the coolant slowly (approximately 8 litres per minute);
this will avoid air pouches within the circuit.
• Place a screen in front the radiator. This will help to reach
fast the optimal working temperature once engine is started
(94°C to 110°C).
• Start engine and keep it about 5 minutes at a rate slightly
above the idle.
NOTE:
If in the first minutes the expansion tank empties totally,
switch off the engine and complete the filling till mouth
(11) of the tank.
• If you have had to stop engine, switch it on again and keep
it about 5 minutes at a rate slightly above the idle over.
Adjust again the refrigerant level and put on the plug of the
spout.
• Speed up the motor till ~ 3.500 rpm to increase fast the
temperature of the refrigerant (94°C a 110°C). Keep the
motor running thus till the air purging of the circuit has
been carried out; the purging is completed when there are
not bubbles in the expansion tank.
Level
Let the motor cool and check that the refrigerant is till the
maximum level on the spout of the tank.
NOTE:
While the air purging of the circuit is carried out check
there are no leaks; and if there are, take appropriate
steps to avoid them.
